    摘要: A speech scrambler is disclosed, in which a frequency spectrum obtained by an orthogonal transform of a time domain signal is divided into a plurality of blocks in the frequency domain. One of the blocks which has energy less than a predetermined value is adaptively replaced by a dummy spectrum. The resulting spectrum is rearranged in accordance with a predetermined rule. The frequency spectrum is subjected to an inverse othogonal transform to obtain a time domain signal for transmission. The orthogonal transform is fast Fourier transform or fast Hadamard transform.

    摘要: An organic hydroxyl compound is reacted with a phosphorylating agent comprising phosphorus pentaoxide and at least one compound selected from the group consisting of water, phosphoric acid and polyphosphoric acid and having a value represented by formula (I) of from 0.5 to 1.0, under such a condition that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2; or alternatively, an organic hydroxyl compound is reacted with the above phosphorylating agent under such a condition that the ratio as defined by formula (II) has a value in the range of from exceeding 3.2 up to 6.4 and then phosphorus pentaoxide is added to the reaction product in such an amount that the ratio as defined by formula (II) has a value in the range of from 2.8 to 3.2 with respect to the total feeds of the starting materials to conduct further reaction. Said process enables the preparation of a phosphoric ester mixture which is excellent in hue and odor, is reduced in the amount of orthophosphoric acid formed as a by-product and contains a phosphoric monoester useful as the component of detergent in an increased amount.
